The US model, 19, told her fans that she was being treated at the Soba Recovery Centre in Malibu, but denied a report that she had been forced to enter the clinic by her family because of intensive partying.

"Apparently I'm in rehab for intensive partying soooo I'm just going to lay pretty low for a bit and maybe get some frozen yoghurt.

"I checked myself into Soba for two weeks to just get away for a little bit. I'm not much a party cat but I am here (to) deal with some emotional trauma and getting the intensive therapy I needed in order to recover."

The teenager, whose parents divorced in 2002 after acrimonious court battles, added: "Some day I'll feel ready to share my story openly without feeling the way I do. Right now I just needed a breather.

"I needed a chance to work on myself and gather all the tools I need to overcome everything that I had been through and rid myself of all the pain I locked away in unreachable places."
